Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7504, here are decompositions:

5 + 7499 = 7504
17 + 7487 = 7504
23 + 7481 = 7504
47 + 7457 = 7504
53 + 7451 = 7504
71 + 7433 = 7504
173 + 7331 = 7504
197 + 7307 = 7504

Showing the first eight; more decompositions exist.
